A word from Katie, the 'Tinkerbell' costume creator:

This my daughter. She went as tinkerbell this halloween (2011). I made the tutu and wings. I got the instructions for the fairy wings from marthastewart.com. It only took 18 gauge wire, girls white tights, scissors, black electrical tape & elastic to make them. I got the instruction video for the "no sew" tutu off of youtube. Scissors, 6 yards of tulle & satin ribbon was all that was needed.
